So I made this Soundwave costume from the original Transformers 80's cartoon! It was great fun, and it's mostly made with cardboard and hot glue. Gumtaped and painted. Used some magnets and velcro along with straps arranged on the inside of the costume. The chest opens to eject a video tape of laserbeak. The chest compartment has speakers to play music and to keep proportions appropiate I'm walking on yoga blocks so my legs doesn't look squashed.
